Free-Float Picatinny Quad-Rail Handguard w/Slots

  • 6727

This is identical to our other Picatinny quad-rails except the weight-saving cutouts (sometimes called Speed Holes) are slots-shaped for a different look.

This is a standard free-floated quad-rail for the AR-15/M-16 platform. It is a free-float design, but a cap (sold separately) may be installed to close the front if your mission requires this.

  • Laser-etched location numbers such as 'T16,' 'B6' etc
  • Monolithic (1-piece) style
  • Includes a barrel nut - this replaces your current barrel nut, if you have one.
  • Has an overhang to line up with the rail on a flat top upper if you have a bit of patience.
  • A standard AR armourer's tool/wrench is required to install the new barrel nut. Tighten to military specification of ~35 foot-pounds.
